The new precision servo gear units PxG® were developed for use in a large variety of applications. They stand for top quality and technical innovation in the detail. A comprehensive modular system allows for the flexible adaptation regarding torque, gear ratio, output geometry or the interface to the servomotor. Exclusive individual elements such as the “Premium Sine Seal” oil seal, the use of SEW GearOil or the bearing system ensure a long service life, even under extreme loads.

From the modular system, three preferential series can be outlined as series of performance classes 5 to 7. Each series follows different requirements. Performance class 5 focuses on the use in dynamic motion sequences with a large number of acceleration and braking processes in intermittent duty. Performance class 6 is suitable for applications with high cyclic duration factor. A service life of 30,000 h can be achieved by modifying gearing and bearings as well as the use of a bellows coupling. The use of performance class 7 is optimal if space is at a premium. Maximum precision is achieved here already in the standard version by a rotational clearance of 1 to 2 angular minutes.

Innovative production and assembly processes ensure shortest delivery times and constant product quality. The relevant data of the final checks is attributed to the real product in the digital twin. Besides providing comprehensive documentation packages, this also enables improved simulation of the planetary gear units in the life cycle at a given gear unit utilization. The wear resistance reached in gearing secures operation through minimum deviations compared to the delivery state – even after many load cycles.

Due to the high positioning accuracy, typical areas of application are a large number of handling applications in the fields of robotics, automation and handling technology as well as machine tools and woodworking machines. The compact design and durability in continuous duty make these gear units ideal for use in food, packaging, printing, paper and textile machines.
